Arp 94 NGC 3227

Arp 94 is a pair of interacting galaxies located over 50 million light-years away from the Earth in the constellation of Leo (the Lion). It consists of the large, unbarred spiral galaxy NGC 3227 of about 90,000 light-years across, and the smaller dwarf elliptical galaxy NGC 3226. The pair is receding from us at a little over 1150 kilometers per second. The nucleus of NGC 3226 appears to contain an active galactic nucleus (AGN). The nucleus is a strong source of both radio and X-ray emission that is expected from the environment around a supermassive black hole. The X-ray emission may also be variable, which is also expected in the environment of a supermassive black hole.

NGC 3227 contains a Seyfert nucleus, a type of AGN, with an active central supermassive black hole. (Such Seyfert galaxies are galaxies with extremely bright nuclei that produce spectral line emission from highly ionized gas. The centers of Seyfert galaxies AGNs, and usually contain supermassive black holes with masses between 10 and 100 million solar masses.)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
